## Description

* Smart Contract System Design: Contribute to the architecture of smart contract systems for Ondo's evolving product suite - covering new chain deployments, novel DeFi interoperability and bridging solutions, and DeFi protocols - with security, operability, and long-term maintainability designed in from the start.
 * Lifecycle Security & Operations: Help ensure contract security not just at deploy but across the full lifetime of the system - including upgrade safety, administrative controls, and the operational guardrails that keep things safe as they evolve.
 * Tooling & Automation: Build tooling and automated systems that let non-technical teammates safely view, monitor, and manage contracts without writing scripts or touching raw chain operations directly.
 * Cross-Functional Integration: Connect smart contract design to the rest of the product - helping the web team integrate cleanly, helping operational teams monitor and manage without direct scripting, and ensuring design decisions flow sensibly through to end users.
 * Collaborative Execution: Work closely with senior engineers and leadership on high-impact blockchain projects, contributing sound technical decisions aligned with long-term goals.
